position, wherein the shifting slide bar connected thereto holds the hooks out of enagement with the numeral keys, the shifting lever being moved to this position by the movement of the platen to a position corre sponding to the writing of upper case characters.

Fig. 8 is a perspective view, showing a detail of the shifting lever and the connection of the compensating mechanism thereto.

Referring more particularly to the separate parts of this invention as embodied in the form shown in the drawings, 1 indicates letter keys and 2 numeral keys, which are secured to key levers 3 which actuate, through the intermediary of rockers 4, type bars 5, so as to swing the latter up rearwardly against the front side of a platen 6, which is rotatably mounted on the platen frame 7. The platen frame 7 is hung by means of hooks 8 on the frame of the carriage 9, so that it may swing from lower position, corresponding to the writing of lower case characters, to an upper position, corresponding to the writing of upper case characters. To accomplish the shift from lower to upper case, the platen frame 7 is provided with a roller 10, which rests on a shift rail 11 secured to a pivotally mounted shift frame 13. The shift frame 13 is actuated in the usual manner from one or more shift keys 14, which are secured to shift key levers 15'. each having an arm 16 which bears against the shift frame 13, and is adapted to rock the same so as to elevate the rail 11 and thus the platen frame 7 at each actuation of either of the shift keys 14.

The carriage 9 normally tends to feed in a letter-spacing direction under the pull' of a spring barrel 17, and is controlled in its movement by an escapement mechanism, indicated generally at 18, which may be of the usual Underwood type, wherein the carriage is permitted to jump a letter-space step at each actuation of a key.

The numeral keys 2 may actuate a valuating escapement mechanism or indexing device, indicated generally at 19, so as to con trol the computing of one or more computing heads 20. To accomplish this, the numeral keys may be Provided with any suitable form of coupling means, such as a pair of jaws 21 and 22 spaced apart from each other and open at one side so as to receive, in the case of each numeral key. a hook 23. Each of the hooks 23 is pivotally mounted on a bell crank or rocker 24. so that when a key is actuated and a hook 23 is in engagement therewith, the rocker 24 will be manipulated to draw on a rod 25, which is connected at its forward end to a bell crank 20 mounted on a pivoted at 27 so as to plunge a jack 28 against one of a series of pins 29 movably valnating wheel 30. There is one of thesdjacks for each of the numeral keys 1 to 9. Their action is suchthat each will force the opposed pin 29 through the valuating wheel 30, so that it projects on the opposite side thereof and W111 come in engagement with an escapement wheel 31 when the valuating wheel 30 is permitted to rotate by the release of the escapement wheel 31, which is normally held by a larger fourtoothed escapement wheel 32 engaging with one of a pair of detent lugs 33 on a rock shaft 34. The rock shaft 34 is acutated at each manipulation of one of the numeral keys 1 to 9, so as to permit the escapement of the wheels 31 and 32, and thus bring the next projected pin in engagement with the escapement wheel 31, whereby the valu ating wheel 30 has been permitted to rotate an amount corresponding to the particular numeral key struck. The rocking of the shaft 34 may be accon'iplished by the bell cranks 26 engaging a collar 120 and press- 1 I 1 ing the same to one side against the tension of a spring 121, so as to rock a lever 122 connected to this collar and also connected to an arm 123 on the rock shaft 34 through the intermediary of a link 125. The spring 121 will return the collar and the rock shaft 34 after the pressure on the numeral key has been removed.

The valuating wheel 30 has connected thereto a gear 35 which meshes with a corresponding gear 36 driven by a bevel gear 37. The bevel gear 37 meshes with bevel gears 38 and 39 on shafts 40 and 41 respectively. The shaft 41 is driven by a motor 42 through the intermediary of a slip clutch (not shown) and intermeshing bevel gears 43 and 44, the latter of which is on the shaft 41. p

The shaft 40 is also provided with a bevel gear 45 meshing with a bevel gear 40 on a shaft 47.

The shaft 47 is provided at its upper end with a bevel gear 48 meshing with a bevel gear 49 on a master wheel shaft 50. A master wheel 51, mounted on the shaft 50 in such manner as to be rotated thereby, is brought successively into engagement with internal gears 53 of a series of computing wheels 52 by a step-by-step movement corresponding to the step-bystep movement of the typewriter carriage 9. Such relative movement may be effected by mounting the computing wheels in a movable carriage which may be connected to the typewriter carriage, as shown. for example, in my prior Patent, No. 1,020,082, granted March 12, 1912. Means for causing such step-by-step movement of the typewriter carriage and computingmechanism is common to Underwo d-lvright machines, and, in view of the description in the above-mentioned patent, it

is deemed necessary to specifically describe eas es rig Wheel by tens carrying iceted generally 59, which rt of my invention, and elderly described this "ent to sr-iy however, that chenism obtains its inediery of gearing correspond The shaft .L in by meshing tie shaft 6% in turn in the shaft 4L1,

tang lever 73 is carriage operate it is provided with a beeroverlying and engaging" a pin 85 on the 39333 pensating lever The pin 85 has secured thereto a spring 86, which is secured at its upper end to av fixed pin 87, The spring is stronger than the spring 86, so that it i revents the movement: of the shifting lever 73, under the pull of the spring; by hold ing the compensating; lever 83 immovable against the pull brought thereon through the stop arm 84:. It will be seen however, that the movement of the shifting lever 73, in the direction of pull of the spring 86 and thus the n'ioveinent of tie floating interponent or compensating lever 83,, under the pull of the spring 86, is limited by one arm 88 of the upper l'iifurceted end of the shifting lever 73 engaging the pivot '7? or the ezo tension thereof; as indicated in Figs. 6 and 7. The other (u-n1 89 of the bifurcation will likewise limit the movement of the shifting lever 73 in the opposite direction, as indicated in Fig. 3.

In order to do any computing it is neces Sony to overcome the opposition of the spring 86, and thus permit the spring 80 to manipulate the shifting lever "23 from the position indicated in Fig. l to the position indicated in Fig. 3. For this purpose on automatic control by the typewriter carriage is provided. The pin has connected es thereto a link 90, which is secured at its. lower end to an arm 91 of a bell crank lever 92, a portion of which is formed by a shaft 93 extending reerwardly Where it is pro vided with :1 second arm The arm 94. is connected by it link 95 to e controlling hell crank lever 96 operated by the typewriter carriage.

.lhis controlling hell crank lever 96 for the purpose of having the typewriter 1.05 log surface 97 having inclined com surfaces 98 and 99 adapted to permit the hell crenl: 96130 be thrust i'earwardly by an extension 1000f one or more teppet 101 on the typewriter carriage, and in so doing'rocl; "the bell crank 96 so as to pull down on the pin 85 through the connecting linkages. The tappets 101 may be arranged at any desired intel-vols in paired slots 102 and 1023 located at letter space intervals on a rack lO-l. This rock 104- is secured so as to move with the carriage 9, and may be the usual column stop rock so that the tappets 101 may act es colunm stops, and, by engegen'aent with colunm stop plungers or counter stops i03 determine the position of the carriage 9 when said counter stop are actuated by column key levers 106 in it nienner connnon to the Underwood typewriter.

Even While the hearing surface 9? is engagement with one of the tay'niets .lol sc that the typewriter carriage tends o melee the hooks 23 engage the numeral 3 v sired, as for example, when the'platen frame is shifted from its lower to its upper position, in which upper case position the characters written with the numeral keys are not numbers, so that to avoid errors the nu ineral keys should not operate the computing mechanism. To accomplish this, the shifting frame 13 is connected to a lever 107 by a pin-and-slot connection 108, so that the lever 107 will be rocked about its pivot 109, whereb its forward end will be depressed when t e platen is shifted to upper-case position, so as to bend a throw-out 110 into engagement with the arm 88 of the shifting lever 73, with the result that said shifting lever 73 may be forced from the position indicated in Fig. 3 to the position indicated in Fig. 7. The throw-out 110- is shown in the form of a cam arm loosely mounted between collars on the pin 87, and bent so as to be readily'engaged by the lever 107 and so as to readily engage the fork or arm 88 of the shifting lever 73. Such a movement of the shifting lever 7 3 may occur when the sector gears 75 and 7 6 are in the position shown in Figs. 1, 4 and 5, (in which conditions the movement is idle), and even when the shifting lever 7 3 is in the position shown in Fig. 3, in which latter case the shifting lever can be moved against the tension of the spring 80 and then disconnects the hooks 23 by forcing the shifting bar 69 from the position indicated in Fig. 3 to the position indicated in Figs. 6 and 7.

The controller can be actuated so that it will hold the hooks 23 out of connection with the numeral keys 2. To do this, it is merely necessary to rotate sector gears 75 and 76 from the position shown in F igs. 1,

3, 4 and 5 to the position shown in Fig. 6, in which position the sector gears will be locked by the spring 80 being shiftedto the other side of the pivot 74, and tending to pull the shifting lever 73 and the sector gear 76 toward each other. The movement of the sectorgears 75 and 76 is however limited by. providing at the ends thereof enlarged teeth 111 and 112, which, by engagement with each other and with the smaller spaces between the teeth, will prevent the further movement of the sector gears. The stop 181 will be shifted to the position indicated in Fig. 6, so that it will be out of engagement with the toe 182, and therefore there will he no pull on the gear sectors 75 and 76. The spring 86 however will still act, through the intermediary of the pin 85 and the stop arm 84, to force the shifting lever 73 into the position indicated in Figs.4 and 6. Even if the carriage-controlled mechanism should be actuated, as

indicated in Fig. 6, there will therefore be no tendency to bring the shifting lever from its disconnecting position tp its connecting position so that the typewriting mechanism a stronger, pulling on the arm can be actuated without actuating the comsired to use the computing mechanism as I well as the typewriting mechanism the controller is manipulated so that its parts occupy the position indicated in Figs. 1, 3, 4 and 5, in which the spring 80 will be under a. tension normally tending to shift the shifting lever 73 and thus the bar 09, so as to bring the hooks 23 into connection with the numeral keys 2. This action, however, is prevented by the spring 86, which is 84, through the intermediary of the pin 85, and thus holding the hooks in the position indicated in Figs. 1 nd 4. As soon as the carriage has been moved either by actuation of character keys or tabulating keys to a position corresponding to a column on the work sheet in which it is desired to compute, then one of the tappets 101, which has been previously placed in a corresponding position in the rack 104, will come in engagement with the controlling lever 96, so as to force the same away from the rack 104: until the bearing surface 97 engages the extension 100. This movement will, through the intermediary of the connecting linkages, pull down on the pin 85 against the tension of the spring 86, whereby the latter will 10 longer be opposed in its pull to the tension of the spring 80 and to the movement of the shifting lever 84, and further whereby the tension on the spring 80 will be increased by the toe 182 forcing the stop 181 and thus the sector gear 76 farther away from the pin 82. It will thus be seen that not only is the tension on the spring 86 overcome, but the tension on the spring 80 is aided to positively draw the hooks 23 into engagement with the jaws 21 and 22 and thus complete the connection between the computing mechanism and the numeral keys of the typewrit'ing mecha to the position indicated in Fig.7, wherein it will have forced the shifting lever 73 from the osition indicated in Fig. 3 to the position indicated in Fig. 7. This may often happen while the compensating lever 83 is in the position indicated in Fig. 3, as the spring 80 will expand to permit the shifting lever 73 to move from the position indicated in Fig. 3 to the position indicated in Fig. 7.

incense it desired to use the typewriting ism without the computing Incchw ,iy necessary to shift the the controller from the position in Fig. 1 to the position indicated wherein there Will be no tendency ing 80 to draw the hooks 23 into age With the jaws 151 and 252, and in fact the tension of this spring 80 will. act tohoid the shifting lever 73 in the poo Yon indicated in Fig. 6, corresponding to the disconnected relation of the hooks.

with respect to the numei'al keys 2. Even though the tappets 101 should. actuate the re ,itrolhng lever 96, the spring 86 would keys.

merely be expanded and there would be no :i'orce tending to connect the hooks QS v ith the numeral keys Variations may be resorted to Within the scope of the invention, and portions of the n'nprovements may be used without others.
